Looking at the html files, after the heading 'Capital punishment': CAPITAL PUNISHMENT</span></span></span></span></span></span></span></span></div>

there are 15 consecutive closures. Random looks at similar points in e.g. David Copperfield or Edwin Drood seem to have only half-a-dozen or so.
I wonder if this has somehow bumped up against an internal limit.
This is a chapter heading in DC: IV. I Fall Into Disgrace</span></span></div>
